Application filed-September 19, 1925 Serial No. 57,327.

vision of means whereby a bobbin may bev wound without removing it from its case.

,Further objects of the invention will ap-- pear from the following description anc appended claims.

In the accompanying drawings, Figs. 1 and 2 are top and side views, respectively, of the looper which comprises a bobbin case; Fig. 3 is the cover for'the bobbin case; Figs. 4 and 5 are side and top views of the bobbin; and Fig. 6 is a view of the winding crank. Y e

In the illustrated embodiment of the invention, 1 denotes the looper bodyhaving a cylindrical recess therein constituting a bobbin case and having a rib 4: on its outer circumference whereby it may be retained in a machine in the ordinary manner.

i The looper also comprises the loop seizing beak 8 and neck 9 which, respectively, seize the needle thread loop and carry it around the looper.

-One side of the looper is permanently closed by a wall 11, while the opposite side is adapted to be closed when in use by means of a cover plate 13, which is detachably se-' cured to the looper body by means of screws 14 and 19, adapted to engage holes 2 and 6 in the looper body.

Elongated holes 3, 5 and 7 are provided in the looper body to reduce the weight of the parts.

Holes and 15 are provided'in the looper body and cover plate to guide the bobbin thread which is tensioned by spring 1-6 held in position on cover plate 13 by means of a screw 17.

Bearing holes 12 and 18 are provided in the looper body and cover plate and are adapted to rotatably mount therein a bobbin, as shown in Figures 4 and 5, which comprises'the shaft 22 and flanges 20 and 21. The shaft 22 is provided with a square hole 23.

Figure 6 shows a winding tool made in H the form of a crank having a body portion 26 provided with an extension 25 extending at right angles thereto, the extension being provided at its outer end with an operating handle 24. The body'portion 26 has a squared extremity 27 adapted to fit into the square hole 23 in the bobbin shaft.

By the above construction, when the thread on the bobbin becomes nearly exhausted, the end of thread from a supply may be attached to that remaining'on the bobbin and wound thereon by means of crank 26, which may engage the square hole 7 23 in the bobbin shaft 22 through opening 18 in the cover plate. By this means the supply may be readily replenished without opening the bobbin case.

The various features of novelty of the device shown and described are of my invention.

Having thus set forth the nature of the invention, what I claim herein is 1. In combination, a looper comprising a covered bobbin case having an opening therein, a bobbin having a shaft journal'ed in said case,.said shaft being accessible from the v outside of the case through said opening,

and a winding tool, said shaft having means adapted to be engaged by said tool whereby the bobbin may be rotated while enclosed by said case.

2. In combination, a looper comprising a bobbin case, a cover for said case, said cover I having a hole therein, a bobbin having a.

shaft journaled in'said hole and accessible. from the outside of said case, and a windingv tool, said shaft having means adapted to be engaged by said tool whereby the bobbin may be rotated while enclosed by said case.

3. In combination, a looper comprising a covered bobbin case having an opening therein, a bobbin having a shaft journaled in said case, said shaft being accessible from the outsideof the case through said opening and having a square hole in one end thereof,

and a winding tool having a squared end adapted to fit insaid hole, whereby the bobbin may be rotated-while enclosed by said case. v
